4.6.6 OK, Apply, and Cancel Buttons
The Cancel button undoes any changes that have been made in register bit
values, so the register panel matches the current state of the EVM registers.
The Apply button sends the current bit values shown on the register panel to
the EVM and stores them in the EVM registers. The OK button performs the
same function as the Apply button and simultaneously closes the register
panel.
